SparkFun ESP32 Qwiic Pro Mini

Say hello to the next generation of Pro Mini boards - the SparkFun ESP32 Qwiic Pro Mini houses the powerful ESP32-PICO-MINI-N8R2 from Espressif on our compact Pro Mini footprint with 2MB of PSRAM. With two individually controllable CPU cores, adjustable CPU clock frequency, a co-processor that can be used in situations that require minimal computing power, as well as a rich set of peripherals such as capabilities for an external SD card interface, capacitive touch sensors, ADC, DAC, Two-Wire Automotive Interface, to Ethernet, high-speed SPI, UART, I²S, and I²C, this board is a powerhouse in a tiny little package. Best of all, utilizing our handy Qwiic system, no soldering is required to connect this Pro Mini to the rest of your system.

The integration of Bluetooth® (specifically Bluetooth SPP), Bluetooth LE, and WiFi ensures that a wide range of applications can be targeted and that the module is all-around: using WiFi allows an extensive physical range and direct connection to the Internet through a WiFi router while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection. The sleep current of the ESP32 chip is less than 5μA, making it suitable for battery-powered and wearable electronics applications. The module supports a data rate of up to 150Mbps and 20dBm output power at the antenna to ensure the most comprehensive physical range.

**Note:** Unlike other ESP32 boards, this device requires user interaction to program. To program the device, hold down `GP0` while resetting it. This is a simple process, but it is not automatic.

*The [SparkFun Qwiic Connect System](https://www.sparkfun.com/qwiic) is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.*
